The book starts studying Numbers, Actually real numbers and constructs them from rational numbers with Dedekind Cuts, Which we expect to see these parts in a Set theory book or something about Math bases. This chapter is well written, But not what we think of the word "Analysis".
Second chapter is about Metric Spaces, I think it's the best chapter of this book,Very clear and educational, not theorem_Lemma style, it seriously tries to "teach" you the concepts, This chapter_As the name tells you : A taste of topology_ doesn't have very analytic taste again. But it's a very good start to understanding Topology even though Maybe it does not teach you topology directly.
Rest of the book has more Analytic Topics, Like Derivative, Integral, Function Spaces. These chapters are more familiar and somehow you can see them as applications of chapter 2.
The book is not Rich enough on multivariable part. Maybe it's better to look at 'Calculus on Manifolds' by Spivak for this topic.
I repeat again, the book really cares about how you will learn concepts, it is full of figures, examples, questions. Very good book to read in two semesters for an undergraduate student.
